So I have some new rs4 replicas with a center bore of 57.1 do I need to get hub centric rings? I have a 99 2.8 a4 sport package.

I just bought some 18in flik artic wheels that I put on and I had a slight vibration between 40-70mph. Then I realized what those plastic rings that came with my wheels were for. I put those on and the vibration went away completely. I had been told sometime you need them and sometimes it makes vibration worse. As for the size of the ring, not sure. But i think i saw it when I was searching in this forum. GL.

If the inside bore of your wheels are 57.1 then you need no concentric rings because thats the same size that the hub is.

Good Luck...

very cool thanks for the help. i should be putting them on this coming weekend...I'll throw up some pictures.
